True, tho I suspect that the basic algorithm many use is "run it through
trang." ;-}

Yes, but looking at the code I noticed MSV creates a list of types collected
in the course of validating an attribute. I thought perhaps it had the
ability to pass this information on to an application. Eric kind of led me
there with his comment

But maybe not. Eric, is this what you meant?
